Definition
BIOSTOVEYN indicates whether the household has an improved biomass stove, which relies on traditional fuels (such as wood) but is designed to reduce energy consumption and harmful smoke emission. The related variable BIOSTOVENUM reports the number of improved stoves owned by the household.
The information in BIOSTOVEYN is taken from the household record, linked to the record of the woman respondent. This information applies to household residents, not temporary visitors, so researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2").
